WorldView-2 ( WV 2 ) is a commercial Earth observation satellite owned by DigitalGlobe . WorldView-2 provides commercially available panchromatic imagery of 0.46 m (18 in) resolution, and eight-band multispectral imagery with 1.84 m (72 in) resolution. [4]

It was launched 8 October 2009 to become DigitalGlobe's third satellite in orbit, joining WorldView-1 which was launched in 2007 and QuickBird which was launched in 2001. [5] It takes a new photograph of any place on Earth every 1.1 days. [6]

Design [ edit ]

Ball Aerospace built the spacecraft, which includes an optical telescope that can image objects 18 in (460 mm) in diameter.

Launch [ edit ]

WorldView-2 was launched 8 October 2009 from Vandenberg Air Force Base on a Delta II flying in the 7920 configuration. The launch vehicle was provided by the United Launch Alliance and launch services were administered by Boeing . [7]

History [ edit ]

On 19 July 2016, the Joint Space Operations Center reported a debris causing event of at least 9 observable pieces, after which DigitalGlobe demonstrated the satellite to still be functional by releasing an image of downtown Oakland, California . [8] [9]
